Description
La présente invention concerne un implant intrao-The present invention relates to an intra-
culaire destiné principalement à remplacer le cristallin naturel en ses lieu et place, après opération de la cataracte, c'est-à-dire à l'intérieur du sac capsulaire formant l'enveloppe du cristallin naturel. La technique opératoire de la cataracte la plus utilisée à ce jour est celle dite de phaco-émulsification, Cular intended mainly to replace the natural lens in its place and place, after cataract operation, that is to say inside the capsular bag forming the envelope of the natural lens. The most used cataract operating technique to date is the so-called phacoemulsification technique,

La phacoémulsification a comme avantage de n'avoir besoin que d'une incision minimale pour l'introduction dans l'oeil15 de la sonde nécessaire à l'ablation de la matière cristal- capsular to be able to place a lens implant there. The advantage of phacoemulsification is that it requires only a minimal incision for the introduction into the eye15 of the probe necessary for the ablation of the crystal material.

Or pour qu'un implant puisse être maintenu dans le sac capsulaire, il faut qu'il possède une dimension suffisante afin d'assurer un bon centrage de l'optique, même après une rétraction capsulaire. Pour cette raison le diamètre total de l'implant est de l'ordre de 11 à 12 mm. Par ailleurs, il est pratiquement impossible et en tout cas mal commode, même avec des implants souples et pliables, de25 conserver cette petite incision que le chirurgien agrandit le plus souvent, au détriment des propriétés optiques de la However, for an implant to be able to be kept in the capsular bag, it must have a sufficient dimension to ensure good centering of the optics, even after a capsular retraction. For this reason the total diameter of the implant is of the order of 11 to 12 mm. Furthermore, it is practically impossible and in any case inconvenient, even with flexible and foldable implants, to retain this small incision which the surgeon most often enlarges, to the detriment of the optical properties of the
cornée dans laquelle elle est réalisée. cornea in which it is made.
En outre, dans les implants connus, la partie haptique de l'implant n'appuie pas de manière uniforme sur la partie équatoriale du sac capsulaire, ce qui conduit à In addition, in known implants, the haptic part of the implant does not press uniformly on the equatorial part of the capsular bag, which leads to
l'apparition de plis de sa partie postérieure, qui provo- the appearance of folds in its posterior part, which provo-
quent une baisse de l'acuité visuelle même sans fibrose excessive. Il faut alors le plus souvent avoir recours à une intervention ultérieure par laquelle on procède à un a decrease in visual acuity even without excessive fibrosis. It is then most often necessary to have recourse to a subsequent intervention by which one proceeds to a
découpage de la capsule postérieure par laser YAG. cutting of the posterior capsule by YAG laser.
Parfois, le bord de l'ouverture antérieure du sac capsulaire (ouverture due à la capsulorhexis) peut adhérer sur le pourtour de l'optique provoquant la création d'une chambre fermée entre l'optique de l'implant et la partie postérieure du sac qui se remplit petit à petit de matière blanchâtre et non transparente. Ce phénomène demande également d'intervenir ultérieurement en découpant au moyen du laser YAG cette partie postérieure. Cette complication est appelée "after cataract" (AJO avril 1998 p. 426).10 Par la présente invention, on entend remédier à ces inconvénients au moyen d'un implant en deux parties dont chacune d'elle est, une fois pliée, d'une taille suffisamment faible pour pouvoir être aisément introduite Sometimes the edge of the anterior opening of the capsular bag (opening due to the capsulorhexis) can adhere to the periphery of the optics causing the creation of a closed chamber between the optics of the implant and the posterior part of the bag which gradually fills with whitish and non-transparent material. This phenomenon also requires intervention later by cutting this posterior part by means of the YAG laser. This complication is called "after cataract" (LAO April 1998 p. 426) .10 By the present invention, it is intended to remedy these drawbacks by means of an implant in two parts, each of which, once folded, d '' small enough to be easily inserted

A cet effet, l'invention a donc pour objet un implant intraoculaire destiné à former un cristallin artificiel logé dans le sac capsulaire, qui comporte une première pièce en forme d'anneau réalisé en un matériau To this end, the invention therefore relates to an intraocular implant intended to form an artificial lens housed in the capsular bag, which comprises a first ring-shaped part made of a material

te. Ce diamètre est compris entre 7 et 9 mm. you. This diameter is between 7 and 9 mm.
L'anneau peut être plié de manière à présenter une très faible dimension (deux ou quatre fois la plus grande dimension de sa section) ce qui permet une introduc- tion aisée à travers une incision de petite dimension. En outre la pièce centrale de l'implant est de dimensions5 beaucoup plus réduites que celles des implants usuels et peut donc être également aisément introduite. Enfin, une fois logée à l'intérieur de l'anneau, dans sa goulotte, la pièce centrale de l'implant ne subit plus aucune contrainte de la part du sac capsulaire si bien qu'aucune déformation10 ne peut l'affecter, qui en modifierait ses caractéristiques optiques. De ce fait, cette pièce centrale peut être réalisée dans un matériau plus souple que celui utilisé The ring can be folded so as to have a very small dimension (two or four times the largest dimension of its section) which allows easy introduction through a small incision. In addition, the central part of the implant has much smaller dimensions5 than those of conventional implants and can therefore also be easily inserted. Finally, once housed inside the ring, in its chute, the central part of the implant no longer undergoes any constraint from the capsular bag so that no deformation10 can affect it, which would modify its optical characteristics. Therefore, this central part can be made of a more flexible material than that used

Dans un mode préféré de réalisation, l'anneau comprend une armature interne en forme de jonc en matériau élastique qui coopère au meilleur dépliement de l'anneau dans le sac capsulaire et à une meilleure adaptation de In a preferred embodiment, the ring comprises an internal frame in the form of a rod of elastic material which cooperates with the best unfolding of the ring in the capsular bag and with a better adaptation of

A la figure 2, on a représenté en trait mixte 1 la forme du sac capsulaire lorsqu'il constitue l'enveloppe du noyau cristallinien naturel. L'implant selon l'invention représenté aux figures 1 et 2 comporte un anneau 2 dont la surface extérieure 3 est conformée de manière à être sensiblement identique à la forme du sac capsulaire 1 dans sa région équatoriale, c'est-à-dire dans sa région de plus In Figure 2, there is shown in phantom 1 the shape of the capsular bag when it constitutes the envelope of the natural crystalline nucleus. The implant according to the invention shown in Figures 1 and 2 comprises a ring 2 whose outer surface 3 is shaped so as to be substantially identical to the shape of the capsular bag 1 in its equatorial region, that is to say in his more region
grand diamètre.large diameter.
La surface intérieure 4 de cet anneau est d'une forme sensiblement torique de manière à réaliser une goulotte interne de sorte que cette surface intérieure 4 définit avec la surface extérieure 3 une partie équatoriale massive pour l'anneau 2 et deux lèvres 6 et 7 qui s'étendent de chaque côté de cette partie massive 5. Ces lèvres 6 et 7 sont tournées vers l'intérieur de l'anneau et on remarquera que le bord interne de chaque lèvre délimite un cercle de 7 mm de diamètre environ et la distance d antéro-postérieure entre ces lèvres est de l'ordre de 2 mm, donc supérieure à l'épaisseur de la pièce centrale de The inner surface 4 of this ring is of a substantially toroidal shape so as to produce an internal chute so that this inner surface 4 defines with the outer surface 3 a massive equatorial part for the ring 2 and two lips 6 and 7 which extend on each side of this massive part 5. These lips 6 and 7 are turned towards the inside of the ring and it will be noted that the internal edge of each lip delimits a circle of approximately 7 mm in diameter and the distance d anteroposterior between these lips is of the order of 2 mm, therefore greater than the thickness of the central part of
l'implant. Cette distance sera comprise entre 1,1 et 2,25 mm. L'anneau 2 constitue donc un extenseur du sac capsu- the implant. This distance will be between 1.1 and 2.25 mm. The ring 2 therefore constitutes an expander of the hooded bag.

Le matériau dans lequel est réalisé cet anneau est un matériau souple et pliable, par exemple une matière The material in which this ring is made is a flexible and pliable material, for example a material

vrer sa forme initiale lorsque l'anneau est introduit dans le sac capsulaire après avoir été plié et, d'autre part résister aux efforts de contraction qu'il subit de la part35 du sac capsulaire. Pour augmenter ces propriétés, on peut de manière avantageuse introduire à l'intérieur de l'anneau 2 une armature en forme de jonc 8 qui peut affecter une section circulaire ou une section du genre rondelle plate comme représenté, les faces parallèles de cette rondelle étant parallèles au plan équatorial de l'anneau. Le matériau de ce jonc sera de préférence élastiquement déformable, du type PMMA ou en PROLENE (marque déposée) qui est un polyamide bien toléré par l'oeil. L'implant selon l'invention comporte également ver to its initial shape when the ring is introduced into the capsular bag after having been folded and, on the other hand to resist the contraction forces which it undergoes on the part of the capsular bag. To increase these properties, it is advantageous to introduce inside the ring 2 a rod-shaped reinforcement 8 which can affect a circular section or a section of the flat washer type as shown, the parallel faces of this washer being parallel to the equatorial plane of the ring. The material of this rod will preferably be elastically deformable, of the PMMA type or of PROLENE (registered trademark) which is a polyamide well tolerated by the eye. The implant according to the invention also comprises
une pièce centrale 9 qui porte la partie optique de celui- a central part 9 which carries the optical part of it
ci et qui de ce fait affecte la forme générale d'un disque biconvexe. Le matériau dans lequel est réalisée cette pièce centrale est également un matériau souple et déformable du genre hydrogel, acrylique hydrophile ou silicone. Cette pièce centrale, outre le disque proprement dit dont la circonférence est notée 10 aux dessins, possède des pattes radiales ou des protubérances 11 qui viennent se loger à l'intérieur de la surface concave interne 4 de l'anneau en forme de goulotte. L'extrémité de ces pattes 11 est circonscrite dans un cercle dont le diamètre est sensible- ment égal au diamètre équatorial de cette goulotte 4, c'est-à-dire son plus grand diamètre. Aux figures 1 et 2, les pattes 11 sont pourvues d'orifices 12 qui permettent notamment de faire tourner la pièce centrale de l'implant dans l'anneau si ce mouvement ci and which therefore affects the general shape of a biconvex disc. The material in which this central part is made is also a flexible and deformable material of the hydrogel, hydrophilic acrylic or silicone type. This central part, in addition to the disc itself, the circumference of which is noted 10 in the drawings, has radial lugs or protrusions 11 which are housed inside the internal concave surface 4 of the ring in the form of a chute. The end of these legs 11 is circumscribed in a circle whose diameter is substantially equal to the equatorial diameter of this trough 4, that is to say its largest diameter. In FIGS. 1 and 2, the legs 11 are provided with orifices 12 which make it possible in particular to rotate the central part of the implant in the ring if this movement
est nécessaire lors de sa mise en place. is necessary during its installation.
A la figure 3, la pièce centrale 9 de l'implant possède également un disque central dont la périphérie est notée 10 et des pattes radiales 13 qui donnent à l'implant une forme carrée dont les coins sont abattus. Bien entendu toute autre forme de pièce centrale d'implant peut être In Figure 3, the central part 9 of the implant also has a central disc whose periphery is denoted 10 and radial lugs 13 which give the implant a square shape whose corners are cut down. Of course, any other form of central implant part can be
accommodée à l'intérieur de l'anneau 2. accommodated inside the ring 2.
Dans d'autres modes de réalisation non représen- In other embodiments not shown
tés, la partie haptique de la pièce principale peut être formée par un voile en couronne dont la circonférence externe est logée dans la goulotte. Dans ce cas, pour tees, the haptic part of the main part can be formed by a crown veil, the outer circumference of which is housed in the chute. In this case, for

plant, ce voile sera percé d'ouvertures. plant, this veil will be pierced with openings.
Pour la mise en place de l'implant, le chirurgien procède, après avoir retiré le contenu cristallinien, à la mise en place de l'anneau 2 au travers de l'ouverture qui a servi à l'introduction des appareils de phaco-émulsifica- tion, cet anneau 2 étant replié en deux ou en quatre et introduit dans le sac capsulaire au moyen d'un outil10 tubulaire ou d'une pince appropriée. Le chirurgien contrôle son dépliement à l'intérieur de ce sac, et ajuste sa mise en place au niveau de l'équateur de celui-ci. Il procède ensuite à la mise en place de la pièce centrale 9 de l'implant, elle-même pliée ou roulée en forme tubulaire, et For the establishment of the implant, the surgeon proceeds, after having removed the crystalline contents, to the establishment of the ring 2 through the opening which was used for the introduction of the phaco-emulsifica devices - tion, this ring 2 being folded in half or in four and introduced into the capsular bag by means of a tubular tool or a suitable clamp. The surgeon controls its unfolding inside this bag, and adjusts its positioning at the equator thereof. It then proceeds with the positioning of the central part 9 of the implant, itself folded or rolled into a tubular shape, and

A titre indicatif, on notera que l'anneau possède un diamètre extérieur de l'ordre de 9 à 10 mm alors que la pièce centrale de l'implant a une dimension diagonale de l'ordre de 7 à 9 mm, ce qui est très inférieur aux implants connus. L'anneau 2, outre sa fonction de maintien du sac capsulaire dans un état le plus favorable puisque proche de25 son état naturel, constitue un protecteur pour la pièce centrale qui ne subit aucune contrainte radiale. Il est donc possible de donner aux parties haptiques de l'implant toute forme et toute dimension possible du moment que As an indication, it will be noted that the ring has an outside diameter of the order of 9 to 10 mm while the central part of the implant has a diagonal dimension of the order of 7 to 9 mm, which is very lower than known implants. The ring 2, in addition to its function of maintaining the capsular bag in a most favorable state since close to its natural state, constitutes a protector for the central part which is not subjected to any radial stress. It is therefore possible to give the haptic parts of the implant any shape and any possible dimension as long as
celles-ci assurent son centrage à l'intérieur de l'anneau. these ensure its centering inside the ring.
En particulier, la figure 4 est un schéma compa- In particular, Figure 4 is a comparative diagram
ratif entre un implant usuel 20 et la pièce centrale d'implant 21 conforme à l'invention. Dans un implant usuel, la racine de la partie haptique 22 au voisinage du bord du disque optique doit avoir en général une épaisseur e de l'ordre de 0,5 mm. Le rayon de courbure R de chacune des ratified between a conventional implant 20 and the central implant part 21 according to the invention. In a conventional implant, the root of the haptic part 22 in the vicinity of the edge of the optical disc must generally have a thickness e of the order of 0.5 mm. The radius of curvature R of each of the
faces du disque optique est de 11 mm, si bien que l'épais- sides of the optical disc is 11 mm, so that the thickness
seur E maximale de cette partie optique est de 1,35 mm. The maximum E of this optical part is 1.35 mm.
Dans la partie centrale d'un implant conforme à l'invention avec les mêmes rayons de courbure, on peut se satisfaire d'une racine de partie haptique 23 d'épaisseur el de l'ordre de 0,2 mm, ce qui fait que l'épaisseur El de l'implant au centre de la partie haptique est de l'ordre de 1,05 mm. Grâce à l'invention, il est également possible de réaliser des implants dont la partie centrale peut avoir une partie optique de diamètre plus important que les implants usuels du fait de cette faible épaisseur des zones haptiques. In the central part of an implant according to the invention with the same radii of curvature, it is possible to be satisfied with a root of haptic part 23 of thickness el of the order of 0.2 mm, which means that the thickness El of the implant at the center of the haptic part is of the order of 1.05 mm. Thanks to the invention, it is also possible to produce implants, the central part of which can have an optical part of larger diameter than the usual implants because of this small thickness of the haptic zones.
